Test Review - Electron Configuration (2024-2025)

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers.

The first orbital in electron configuration is 1s².

An s sublevel has 1 orbital.

The principal quantum number 4 has 16 orbitals.

The principal quantum number 4 has 4 sublevels.

The maximum number of electrons in an s orbital is 2.

The maximum number of electrons in a p sublevel is 6.

The maximum number of electrons in a d sublevel is 10.

The maximum number of electrons in an f sublevel is 14.

The order of filling orbitals is: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p.
